Comodo Antivirus not working- error- please help

Hello- I 'm using using Comodo Anrivirus (free version) on a Windows 7 system. It will no longer update or do scans. When I click either I get an error message that says “Update failed. Error 0x80004002. No such interface supported.” Looks like it last updated itself a couple of weeks ago. So, I have no antivirus running now, I believe.

I also run Iolo System Mechanic and it has a warning saying no antivirus detected.

I have tried:

Downloading Comodo Antivirs again twice now - nothein changes.
Uninstall Comodo Antivirus, but it is not on the “remove programs” list in the control panel
I looked up the manual uninstall directions, however I can’t seem to get to the CAV directory to make that work either.

Any ideas?

Thanks so much for any advice!

PS: I did see the post by egeman on windows 7 64 crashes but I am not sure if it applies to this- I am not sure if I have 32 or 64. If that is the issue here, -how do I copy the file exactly to the right place? I have not done much with program files and don’t want to ■■■■■ up the system)

Can you please post what Virus Signature Database Version you have and which Version of Comodo Antivirus.

Thank you.

Product Version 5.5.1957861383
Virus Signature Database Version 0

Please follow the instuctions here to download a virus database as you cannot update from a Virus Signature Database Version 0 it needs to be 1 or higher for a update to succeed.

Your database must have been corrupted at some point for it to be 0

It might be possible you have a correct bases.cav in the CIS repair folder.

Sorry I have no idea why it was corrupted.

I do. There’s a problem with the servers at Comodo - I have not been able to update the defs on any of my PC’s for three days now…

Hello Mightyred. I just answered in the other topic.

Next time please don’t cross post; that is not allowed.

EricJH- Thanks for that.

Dennis2- thank you as well for your help. I followed the link and downloaded the 5.5 version. I unzipped it with 7zip and got a file with one document inside that began with END_USER…cav. I the renamed the document bases.cav, then I rebooted in safe mode and renamed the original file bases.cav located in C: program files/comodo/comodo internet security/scanners to bases.old. I then copied the newly downloaded and renamed bases.cav to this location. I rebooted in normal mode and tried to do a comodo antivirus update and got the same error message as before. I also just tried running a scan- got the same message as well.

Any other ideas on how to fix comodo or at last resort to remove it so I can get something on here to protect my computer? I did download spybot so I could manually scan, but still want to have antivirus. Thank you!

If I recall correctly the “Update failed. Error 0x80004002. No such interface supported” points to a problem with the network connection.

Comodo is currently working on their servers and you may be experiencing a glitch caused by this; I informed one of the admins to see if your case is a possible glitch.

Thanks so much-- I appreciate it and will watch and see if that fixes itself.

As Denis2 stated- it looks like I have a “version 0”. Is that to do with the network connection you mentioned or do I need to fix that somehow? Not too savvy about those things.

Thank you

IF you follow the instructions in the topic Dennis points to you will be able to install the latest available full database.

After that you will need to install the incremental updates that were released after the latest full database.

Did you manage to update the full database as described? If that was successful did the incremental updates work after that?

EricJH, I did follow the directions but was unsuccessful.

I followed the link and downloaded the 5.5 version. I unzipped it with 7zip and got a file with one document inside that began with END_USER...cav.

I also just tried running a scan- got the same message as well.

Any idea on what I did wrong or how to do it correctly?

Thank you!

Hi Jewelergirl,
If I have read this correctly you are saying Comodo is not in the programs/features list in the control panel, if this is correct it sounds like a partial uninstall fail to me. If that is the situation try this unofficial uninstaller tool for comodo products then try a fresh install.
Available for download here.

Also I noticed you said you didn’t know if you had 32/64bit, go to control panel, system and it will be noted there under system, system type.
Kind regards.
